D. None of the above

Answer

To solve the question "Receptor absent over tongue is," we will analyze the options provided and determine which receptor is not found on the tongue.

### Step-by-Step Solution:

1. **Identify the Options**: The options given are:
- A) Thermoreceptor
- B) Gustator receptor
- C) Photoreceptor
- D) None of the above

2. **Analyze Each Option**:
- **Thermoreceptor**: These receptors are responsible for sensing temperature changes. They are indeed present on the tongue as well as on the skin. Therefore, thermoreceptors are **not** the correct answer.

- **Gustator receptor**: These are also known as taste buds and are responsible for sensing different tastes. They are specifically located on the tongue. Thus, gustator receptors are also **not** the correct answer.

- **Photoreceptor**: These receptors are associated with vision and light detection. They are found in the eyes and are responsible for sensing light changes. Photoreceptors are **not** found on the tongue.

3. **Conclusion**: Since photoreceptors are the only type of receptor listed that is absent on the tongue, the correct answer to the question is **C) Photoreceptor**.

### Final Answer:
The receptor absent over the tongue is **Photoreceptor**.
